Gene therapy offers potential vision restoration

A recent study demonstrated the success of an innovative gene therapy in partially restoring vision for patients suffering from retinitis pigmentosa. Six out of ten participants were able to improve light sensitivity and visual task performance using light-stimulating glasses after a single gene injection into the eye. This treatment, known as "gene-based visual therapy," involves delivering a light-sensitive protein to the retinal ganglion cells, allowing them to respond to light and achieve monochrome vision. Although the results are encouraging, the therapy does not currently enable face recognition or sharp vision. Researchers anticipate future improvements that could enable more precise vision within the next 5 to 10 years.
